[root@node2 ~]# nginx -t
-bash: /usr/local/bin/nginx: Permission denied
赋权限
[root@node2 sbin]# chmod /home/nginx chmod: missing operand after ‘/home/nginx’ Try 'chmod --help' for more information. [root@node2 sbin]# chmod 777 /home/nginx [root@node2 sbin]# ./nginx -t -bash: ./nginx: Permission denied [root@node2 sbin]# chmod 777 /home/nginx/sbin
有了全局命令了，和操作权限了
执行了nginx -s stop之后， 报错：
[root@node2 sbin]# nginx -s reload nginx: [error] invalid PID number "" in "/home/nginx/logs/nginx.pid"
解决：
/home/nginx/sbin/nginx -c /home/nginx/conf/nginx.conf
ok了，命令恢复
